The market went up and stayed up, Jim Cramer told his "RealMoney" radio listeners on Monday, despite ongoing heat waves and global unrest. The market is responding at last to the good news we had last week and also to a number of big acquisitions, especially the announcement from HCA ( HCA), Cramer said, adding that investors might finally be willing to acknowledge that "not everything is Intel ( INTC), not everything is 3M ( MMM). "I guess what I'm saying is did we ever get too negative?" Cramer said. Cramer's take on the HCA $21 billion buyout deal is that the healthcare company finally tired of the beating its stock has taken at the hands of options traders and hedge fund managers. He said the business was great, but that analysts were never willing to recognize this, always finding something that made the stock a poor pick. But management believed in HCA's value, he said, and bought the stock even as the market beat it down. He added that Motorola ( MOT) and Coke ( KO) are two more examples of companies that have reported good quarters, but got hit by bearish investors. The lesson here, Cramer said, is that the market is not properly valuing companies. HCA wants to be in charge, he said. Its decision to take the company off the market is the beginning of a wave of similar decisions, thanks in large part to the fact that there are trillions of dollars in private equity waiting to be used.
